In natural language and physical science, a physical object or material object (or simply an object or body) is a contiguous collection of matter, within a defined boundary (or surface), that exists in space and time. Usually contrasted with abstract objects and mental objects. [1] [2]

Mechanics (from Ancient Greek μηχανική (mēkhanikḗ) 'of machines') [1] [2] is the area of physics concerned with the relationships between force, matter, and motion among physical objects. [3] Forces applied to objects may result in displacements, which are changes of an object's position relative to its environment.

In physics, a rigid body, also known as a rigid object, [2] is a solid body in which deformation is zero or negligible. The distance between any two given points on a rigid body remains constant in time regardless of external forces or moments exerted on it. A rigid body is usually considered as a continuous distribution of mass.
